La­belled a weed in the Auck­land re­gion, the cheer­ful blue flow­ers of agapanthus are still a vis­i­ble part of the land­scape. Opin­ions are di­vided. Gar­den­ers who are pro-agapanthus point out that it’s ex­tremely hardy, grows on in­hos­pitable clay, is salt-tol­er­ant, very low main­te­nance and its fleshy roots sta­bilise steep banks. The anti camp say these at­tributes are what make it weedy. One can look at agapanthus as be­ing very good at sup­press­ing weeds but pure stands of agapanthus re­duce bio­di­ver­sity by ex­clud­ing all other species. It is a pro­lific seeder. Seeds are blown short dis­tances, drop down banks or get trans­ported by wa­ter. Rhi­zomes spread when soil is moved or plants are dumped. Ideally you should try to grow low-fer­til­ity or ster­ile va­ri­eties and at the very least dead-head spent flow­ers of fer­tile plants near at-risk ar­eas be­fore the seeds have ripened.
